Modeling of circulatory system with coronary circulation and the POLVAD ventricular assist device

This paper presents an application of a numerical package for modeling and simulation of human circulatory system. The model includes a coronary circulation and the parallel heart assistance. The cases of the simulation of the proper and the pathology circulation conditions, such as left or right heart failure are shown. A description of the coronary circulation system is presented and obtained coronary sinus occlusion simulation results are included. An implementation of the whole package as a part of PExSim application is contained. The identification experiment for the ventricular assist device has been described and different methods of the artificial ventricle modeling are presented. An example of use of a fuzzy logic to presentation the dynamics of the POLVAD device is also included. Advantages of developed simulation platform are discussed.
